Objective To explore the difference of clinical features and laboratory indexs with different vasovagal responses in(head-up) tilt test(HUT) in children with vasovagal syncope(VVS).Methods Forty consecutive children diagnosed with VVS by HUT were analyzed.The vasovagal responses were divided into vasodepressor,cardioinhibitory and mixed patterns.The distribution and different clinical features and laboratory indexs of different response patterns in the VVS were studied.Results The most common vasovagal response was vasodepressor.There was no significant difference in their clinical features,including the motivation,presymptom,frequency and duration of syncope,baseline heart rate and blood pressure,and serum electrolytes among the children with different vasovagal respon-ses.Conclusion Vosodepressor response is the most common hemodynamic pattern in vasovagal syncope in children.

?AIM:To compare the corrected vision and improvement of visual quality after wearing rigid gas permeable corneal lens ( RGPCL) or spectacles in aphakic patients.?METHODS: We selected 29 aphakic patients ( 29 eyes ) caused by different reasons wearing RGPCL and spectacle.The corrected vision, eye condition and visual quality were observed and all patients were followed up for 6mo.? RESULTS: RGPCL was better than spectacle on corrected vision (P<0.05).The patients who wore RGPCL for long had no corneal complications reported. The patients who wore RGPCL had better subjective visual quality than those wore spectacle.?CONCLUSION: RGPCL is a good choice for correcting high myopia and astigmatism for aphakic patients.The patients'compliance is good. Wearing RGPL long has high safety for patients'ocular surface.

Objective To study the value of MRI in the diagnosis of spinal metastasis.Methods MR imaging manifestations of spinal metastasis in 85 cases were retrospectively analyzed.46 cases underwent CT and/or X-ray in the 85 cases.Results Totally 388 metastatic vertebra in the 85 cases were detected by MRI.388 vertebras showed hypointensity on T1WI.354 vertebra showed mixed signal intensity and 34 vertebra showed hypointensity on T2WI.All of the vertebra showed hyperintensity on T2WI/STIR.54 vertebra showed pathologic fracture,53 vertebra were protrusion in postetrior,54 vertebra with appendages damage and paravertebral soft tissue mass presented and vertebral canal involved in 30 cases.18 cases were detected with lesion in 46 cases having X-ray and/or CT data,the positive rate was 39.11%(18/46).Conclusion MRI can detect spinal metastatic lesion early,the extent and degree of the tumors can be judged by MRI exactly.

Objective To investigate the changes and its significance of serum content of soluble CD40L(sCD40L) and C-reactive protein(CRP) in patients with acute cerebral infarction(ACI).Methods The content of serum sCD40L and CRP in 40 patients with ACI and 30 normal controls were measured by enzyme-linked immuno-sorbent assay and immunonphelometry.The content of serum sCD40L and CRP were compared in the patients of different pathogenetic condition and infarction size.The correlation between sCD40L and CRP and pathogenetic condition and infarction size were analysised.Results The contents of serum sCD40L and CRP in ACI group were significantly higher than normal control group(all P

Objective To analyze the clinical features and risk factors of migraine patients with white matter le-sions (WMLs). Methods One hundred ten clinically diagnosed migraine patients who underwent magnetic resonance im-aging (MRI) scans from October, 2010 to August, 2013 were enrolled in Shandong Provincial Hospital. One hundred ten migraine patients were divided into two groups:WMLs group and non-WMLs group based on the presence or absence of WMLs in MRI scans. The clinical features of the patients and location and number of WMLs were investigated. Noncondi-tional multivariate stepwise logistic regression after univariate analysis was used to analyze the data. Odds ratio (0R) and 95 confidence interval after adjustment for possible confounding variables were calculated. Results①There were 36 patients with WMLs among the 110 migraine patients. The incidence of WMLs in migraine patients was 32.7%. The WMLs in migraine patients were predominantly present in the frontal and parietal lobes (59.1%). ② Compared with non-WMLs group, there were significant increases in disease duration (5.3±3.7 vs. 7.6±4.9, P﹤0.01), frequency of head-ache attack (3.5 ± 2.3 vs. 4.6 ± 2.2, P﹤0.05), aura (18.9%vs. 36.1%, P﹤0.05) and family history of migraine (12.2%vs. 44.4%, P﹤0.01) in WMLs group.③The independent risk factors of WMLs in migraine patients were family history of mi-graine (OR=5.995), aura (OR=3.067) and long disease duration (OR=1.165). Conclusions Family history of migraine, au-ra and disease duration are the predictive risk factors of WMLs in migraineurs.

We first report the pharmacokinetics of paeoniflorin ( PF), that is a main component of paeony roots, in dogs by HPLC analysis. The experimental results were shown that after i .v . of 11.25 mg/kg PF in 4 dogs, the curve of plasma concentrations versus times for PF was fitted well to a open 2 compartment model, the T1/2 (?) was 6.29?1.80min T1/2 ( ? ) was 133.41?84.89 min, VB was 0.54 ? 0.10 L/kg, andCL was 3.41 ? 1.01ml/min?kg-1 .The results also were shown that PF was rapidly removed from the blood by kidney and the accumulated recovery amounts of excretion was 36.85% and 79.33% of total i .v . doses during 20 min and 7h administrations respectively. The elimination of PF by liver was lower than by kidney, and the accumulated amount of PF in bile was only 3.77% within 7h after iv.

The management of the scientific research files is an important basic work at the college,which is of great significance to the research work in both school and the scientific research organizations.However,some researchers and managers are lack of file consciousness and the management system remains unadapted to the new condition.These reasons result in the use of the dossiers inadequate or even absent.Therefore,it seems necessary and important for the perfection of the scientific research file work to take essential measures:establishing a scientific and reasonable file system,improving the file management regulation,and increasing the utilization ratio of the dossiers.

Objective To observe the anti-inflammation effect of antidromic electronic stimulation of rat dorsal roots. Methods Cross-excitation between adjacent primary afferent fibers and subcutaneous injection of 2% FM were adopted here as two inflammatory models. The firing rate and mechanical threshold of single units after cross-excitation were collected. The phosphorylated cAMP response element binding protein (p-CREB) level in spinal cord induced by formalin was visualized with immunohistology. Results Antidromic electronic stimulation (ADES) of dorsal roots could significantly inhibit the p-CREB over expression to FM injected in the contralateral hindpaw, and the increase in firing rate and mechanical threshold induced by cross-excitation were also inhibited by the ADES. Conclusion Antidromic electronic stimulation of the dorsal root may produce a systemic anti-inflamma-tion capacity.

Objective To study the effect of nursing intervention on postural hypotension of aged with heart disease.Methods Nursing intervention were gived to the 68 aged patients with heart disease and postural hypotension.The effect of nursing intervention on postural hyporension and hypotension associated symptoms were observed.Results The postural hypotension was improved and the incidence of hypotension associated symptoms were reduced after nursing intervention.Differences were statistically significant(P＜0.01).Conclusion Nursing intervention was effective on the improvement of postural hypotension.
